[solved] Cannot boot from USB-Memorystick

Message

Schattenparker · Post by **Schattenparker** » Wed Jan 14, 2009 7:49 pm

Hi,

I decided to install Gentoo (one of these new weekly tarballs) on my USB-Stick, which is about 8GB; I chose 3.5GB as FAT32 partition and the rest as an ext3 Partition, where gentoo is installed on. This installation was done from a gentoo system running on my laptop, which mounted the Stick as /dev/sda2, via usb-storage.
Gentoo-sources-2.6.28 was put on the stick, and I decided for lilo as bootmanager, because I'm confident with lilo for many years now

.
I do not use an initrd, so all relevent parts went directly into the kernel. First I tried the usual way, putting usb->EHCI, OHCI, UHCI + usb-storage as well as SCSI and BLK_DEV_SD into the kernel, but when trying to boot, the kernel fails to mount the root and ends up with a kernel panic. Newer kernels seem to have a nice feature, they list all available partitions, but only my harddrive was found.
Then there is a second possibility: USB block device. By turning off usb-storage (usb_libusual was always deselected) and putting this block device into the kernel (after mknod /dev/uba2 b 0xb4 2, which seems to be mandatory for lilo to accept the 'root=/dev/uba2'), I was able to boot from the stick on two machines, but two other computers seem not to have created this block device on boot, and show the meanwhile well known kernel panic. As the two partitions of my stick are never listed as possible partitions, there is no reason to believe the kernel could have messed up with SATA-HDDs. Meanwhile I have changed /dev/sda2 into this UUID-notation, without noticing differences; I still prefer the variant via usb-storage, but I'm out of ideas what to try next meanwhile.
It's also a pity there is no boot log or a possibility to scroll back to follow all bootmessages when the kernel hangs.
I made some shots with my digicam, if that could be of help, but have no clue how to post them here or if that is desired on this forum, so please tell me which further information I should provide.

Thank you very much in advance.

The booting from usb task is a tricky one and its taken me a lot of trial-and-error to figure it out.

If you want both usb-1 or usb-2 device support it works best with the HCD drivers (i.e. EHCI/OHCI/UHCI HCD support) compiled as modules and loaded via the initramfs/initrd file (which you don't currently have). If you compile them into the kernel then it doesn't seem to work at all.

If your using genkernel to make your kernel then this is handled for you

.. just in case: don't forget, that USB devices need root mounting delay (kernel option) to avoid panic.

That is also true, but i believe this is a feature that the initrd made by genkernel uses rather than a standard kernel option.

Please correct me if I'm wrong tho

Well, I was / am into hurry, so I added one tip, which I missed some time ago for booting kernel (know almost nothing about genkernel).

This option is available without an initrd/initramfs.

Yes, that's it! Thank you so much!

Meanwhile, I tried a vanilla kernel and configured it once again from scratch (quick&dirty, without UHCI+OHCI, just to see if it could change things, but without success); then changed the kernel-config to boot from my harddrive, and putting those necessary drivers in. Though some options where still configured as modules, I did not compile any modules, so to avoid any confusions.
Here is what dmesg said:
